Hi Emil,
Thank you for the update.
As per the implementation, Schedule control has complete localization support for all the calendar elements such as Date, Time, days. For Custom strings, such as Appointment, InlineView string (AllDay, No Events) will not be localized as default, as we mentioned in the earlier update it can be localized by own custom strings. You can handle text / number by your own for those custom strings, as of now changing the custom strings based on the system / device local with the multiple language in the sample level cannot be achieved.
Regards,
Subburaj Pandian V
